The photocurable liquid silicone composition of the present invention comprises (A) a linear organopolysiloxane having at least two alkenyl groups having 2 to 12 carbon atoms and no mercaptoalkyl group in one molecule, (B ) An organopolysiloxane having at least two mercaptoalkyl groups in one molecule, (C) a branched organopolysiloxane having no alkenyl group and mercaptoalkyl group, (D) a photoradical initiator containing a phosphorus atom, And (E) a hindered phenol compound, which is excellent in storage stability and coating properties at room temperature and low temperature (about 0 ° C.), and quickly cured by irradiation with light of a long wavelength and left under high temperature and high humidity conditions Even so, a cured film having transparency and less turbidity and coloring is formed. |
